My teacher is very old fashioned and she's been telling uys all along that when we're quoting from Macbeth for example we must give the act and scene the quote is from eg "Fair is foul and foul is fair" Act 1 Scene 1. Now every other English class in my school says that it is completely unnecessary - Opinions???
I don't think that it would really matter. if you have learned it, by putting the act and scene in, then i would recommend continuing that way. also it might help with going in order of events :-) all the best
